Giant Water Bug

I was surprised to find this Giant Water Bug trucking across the Carleton College Arboretum. They are common across the northern United States and Canada. They are among our largest bugs and are active all year. They normally live under water. In the fall, these bugs fly about looking for deeper waters where they continue hunting their prey under the winter ice. Often they are attracted by lighted areas at night as the bugs are moving to suitable ponds and rivers.

They eat a variety of invertebrates and tadpoles, salamanders, small fish and even birds (eduwebs). Their larger prey is caught by their powerful front claws and subdued by enzymes injected to the prey’s body. Their bite is painful, but they are otherwise harmless to people.
